Pope Francis, the head of the Roman Catholic Church, who completed his three-day visit to Greece today, said goodbye with a Greek saying.
"In Greek, there is an illuminating saying: o fílos ine állos eaftós, 'a friend is another self'. Yes, other people are the path to discovering ourselves. Good decisions are always about others, not just about ourselves," he wrote on Twitter.
It is worth noting that the quote that the Pope mentioned in his post is from Aristotle's Nicomachean Ethics.
